50hz on Lincoln welder

I have a miller welder but at work we have a old Lincoln weldanpower 225 I've read on here to set your machine by hz I checked the Lincoln today and it was right on 50hz so I checked my meter on grid it said 59.9 so I think its right I checked the rpms it was about 3700 anybody every run into this . Model 8927

Since I've been reading this site I started used 62.5 on my welder and generators works good but when I checked this one at work it was 116 v but 50hz and so I checked rpms it about 3710 or 3720 welds alright and runs grinders I'm going to check it again today it's bugging me I was expecting 60hz

False alarm I was pushing the hz button twice it was giving me % which was 49.9 or 50 whatever that means when I pushed it once it was about right 62.3 to 62.5 sorry about that but thanks that's the first time that's happened to me with this meter I've never had to press it twice when I pressed it once it was staying on volts that's why I was pressing again

62.5 Hz? How about 140!

Can you help me out on my welder? I read in many places that I need 62.5 Hz at high idle no load. SO I went out to check mine. I get 140 Hz and I am only at low idle! Do you know what is going on here? thank you

Many of the Millers have a 100hz outlet, whilst welding. and a low idle setting for power . So you want to turn down your machine if checking on the 100hz receptacle
